BuildKit in depth: Docker's build engine explained
A cool thing about Buildkits LLB is that you can write your own front end to BuildKit. At Earthly, this is sort of a starter task for everyone who joins the team.
My frontend was based on intercal and I don't recommend anyone use it[1].
Buildkit functions a bit like a compiler. I wrote an article once about how it all works. [2]

`COPY –chmod` reduced the size of my container image by 35%
Earthly is great (disclosure: work on it)

Compiling Containers - Dockerfiles, LLVM and BuildKit
Hi, I wrote this, thank you for submitting it. I was trying to teach a bit about compilers and container images at the same time and share some working code examples. The code samples are here and here.

Automating the Building of VMs with Packer
Setting up the VM and all the necessary tools usually takes time and effort. Automating this process would be much faster, more convenient, and significantly less error-prone. While one can write scripts to set up VMs, this approach requires new implementations for each virtualization software technology. Various tools exist for this purpose, but I am going to use Packer because it is open source, widely adopted, and well-supported. It supports all modern VM providers, such as VirtualBox, VMware, KVM, and various cloud providers. It is also highly configurable and can be extended if you need functionality not yet supported by the tool.

AWS Cloud Platform for highly loaded WordPress website
The missing piece of puzzle is the AMI "golden image" that will be used to start the instances in autoscaling group. The AMI has to have NGINX and PHP installed with the list of required modules enabled. The great tool to brew one is hashicorp packer.

The 2024 Web Hosting Report
To manage a VM, you can use something as simple as just manual actions over SSH, or can use tools like Ansible, Hashicorp's Packer and Terraform or other automations. For an app where there is minimal load and security/reliability concern, VMs are still a great option that provide a lot of value for the buck

13.2 ZFS root AMIs in AWS
It is straightforward to build them with packer (I have built AMIs for 13.0 and 13.1, but 13.2 should be exactly the same). I've been meaning to write a blog post about it for a while, but have not gotten to it yet... In any case, what I am doing is using the EBS Surrogate Builder to start an instance running the official FreeBSD 13.2 image with an extra volume attached and run a script to create a zpool on the extra volume and bootstrap and configure FreeBSD 13.2-RELEASE on it. After that packer takes care of creating an AMI out of that extra volume, so you can use it... If you have any issues, let me know, and maybe I will finally get to writing that blog post...

auto-provisioning multiple raspberry pi's
Packer is a tool that can be used to build machine images. Basically, it takes a base image, runs a series of steps to provision that image, and then burns a new image. In my workplace we use it heavily to build AWS AMIs. But it has an ARM plugin that looks to be very very suitable for building customised Raspberry Pi images (my quick read of the doco there says it can go ahead and write the final image to an SD card for you too).
